A new species ofCrepidotus (Crepidotaceae)

Crepidotus ehrendorferi spec. nova (sect.Sphaerula) is similar to the North AmericanC. sinuosus and differs mainly by the anatomy of pileicutis with unseptated, long, slender terminal hyphae and some macroscopical characters. It is compared also withC. applanatus andC. crocophyllus. C. ehrendorferi is a very conspicuous, wood-inhabiting species known up to now from a very old forest reserve close to the city of Vienna (Austria).
